MyBB Community Forums

Ok, I know almost nothing about theming, but with the right guidance, I'd like to be able to do this. If you haven't seen phpBB's prosilver theme, it uses roll over images for their buttons. How would I do that for a MyBB theme? (Please explain it to me like you would a 5 y/o)

This is what phpbb uses

Ok, but what I need to know is how to do this for a MyBB theme.
